I bet on the modified key={idx} property in the Shape element.

I'm calculate the key key={${startAngle}-${arcAngle}} to avoid using index as key I think you just pass series=[x, 0, 0] to the component, can you provide you related code?

I'm using the pie as a gauge for percentage between two choices:

getPiePercentages(){
   const pA = this.getPercentage(0)/2; // getPercentage(0) returns e.g. 25
   const pB = this.getPercentage(1)/2; // getPercentage(1) returns e.g. 75
   return [pA, pB, pB, pA];
}

Which is used as following: <Pie series={this.getPiePercentages()} ... />
